Specification of Letters Patent. Patented June `14C,

Application filed February 18, 1918. `Serial 1Y0. 217,873.

To all whom t may concern.'

Be it known that 1, BURNHAM C. STICK- NEY, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey,have invented certain new and useful Improvements in Typewriting-Machines, of which the following is a specification.

This invention relates to the class of devices disclosed in my application No. 212,215, filed January 17 ,y 1918, in which the capacity of the column-stop-setting-meohanism disclosed in the McLaughlin Patent No. 911,166, dated November 9e, 1909, is increased by the `expedientof adapting a plurality of spurs on a plurality of `shafts to set the various column-stops; whereby it has kbeen possible to secure `at leastasmany different settings asthere are different working positions ofthe spur shafts operated separately; additional selections beingpracticable by using allof the spur shafts-at the `same time.

In the mechanism illustrated in said application and said patent, the column-stops are formed upon the front ends of blades or lcarriers which extent rearwardly in suitable guides, whereby considerable space is `occupied atV the rear of thetypewriter carriage. Insome machines, it is desired to occupy a large part of such space with other mechanism, as,.for `example, the adding mechanism of the well-known Underwood-Hanson combined iypewriting' and adding machine. nOne of the main objects of the presenty invention is to secure the advantages of the device covered in said application, and at the Sametime keep the stop-mechanism from projecting behind'the back of the machine, .as ordinarily built,

. thus avoiding such difficulties as the one above mentioned.

To this end :the column-stop blades or carriers are mounted above thecarriage, advantageously vertically, sozthat the columnf stop proper is at the bottomend ,of the carrier. The column-stops normally stand'too high to be reachedbylany ofthe denomina- .tional Yor counter-stops, which in the usual Underwood typewriter, are arranged below the column-stops and `adapted to be pro-V jected to be effective; eachcolumn-stop is settable downwardly soV as fito be able tostrike any `projected denominational stop. Each stop may be set by one ,or more' suitable shafts rear ofthe typewriter carriage7 and therefore, need not interfere with the adding mechanism or other devices which it may be desired to place at the rear part of the machine, nor will it interfere with using Ina-- chines embodying the present improvements in certain kinds of collapsible` desks, More-t over, certain standard covers, which lit the back of the ordinary typewriting machine rather closely, will also fitfsuchmachines Other features and advantages ,will hereinafter appear.

1n the accompanying drawings,

Figure 1 'is a rear elevation of an Underwood typewriting machine provided with the present improvements.

Fig. 2 is a side elevation upon a largerl scale, to show the arrangement of .the column-stops and the stop-setting shafts.

Fig. 3 is a sectional, side elevation, taken `about centrally ofthe typewriting machine.

As usual in the Underwood machine, i. ythe decimal-tabulating keys 10` operate levers 11 to thrust up rods 12 having decimal stops 13 at their upper ends,and these rodshave lugs 14: for operating a universal bar 15, which, by means of the usual connections, lifts `a; rack 16 provided upon the ,typewriter carriage 17 free of the pinion 18 which controls the rack 16, so that the carriage 17 may run along until arrested at a point determined by the lifted decimal stop 13. Said pinion 1S is connected toan escapement wheel 19, whose motion is controlled by means offdogs 20 operated by a universal bar 21, thealatter being engaged by the heels22 of the typebars 23 as theyv are manipulated bythe lkeys 24, to print upon the paper `carriedupon the platen 25 mounted on said carriage. For simplicity, the machineg'shown herein is :provided with a` shiftless platen. Those who are skilled `in the art will readily ,see how my invention is to be applied to shiftable platen machines.

The Acolumn-stops 26 normally/stand `,at i too high an elevation to bereachedby the decimal stops 13,V and in order to enable any -1 en entlythereof by the Upon the front edge of each blade or carrier 27 are providedtwo or more lugs 28,

which are engageable by setting spurs 29.

carried upon upper and lower shafts 3()V and 31. These spurs 29 are provided upon collars 32 which can be secured at different selected points at. letter-space or other in-4 Ttervals along each shaft 3() and 31, and each collar 32 may have one, two, three or four spurs 29thereon, Ain order to meetthe various requirements One shaft 30 or 31 may ferent settings of the column-stops are possible.- `Each shaft, however, may have more than four working positions, thus increasing the selecting `capacity of the stop-selecting mechanism; and it will be understood that there may be more than two spur shafts, and

Va corresponding'number of lugs may be added to-each column-stop carrier.

Each spur shaft has its spurs so located l thereon that its spurs may bereither effective or inelfectivathe shaft being adapted to rest at an ineffective position intermediate each two effective positions.- Y v When either spur shaft is operated, the other spur Ashaft may be `in a neutral position whereby the stops may bemoved-indeother shaft. ence, each shaft is capable of four working positions and four neutral positions; the

shafts being held' in any of these positions by -Ineans 'of springdetents 33 and notched wheels 34 with whichA they engage; the teeth f 35 Aof' the Wheels being .preferably ratchet .i teeth adapted to prevent backward rotation 4of' the shafts underthetorque produced by the springs 43.

Each shaft 30,31 may be provided with a thumb'wheel` 36 for turning` the same, and upon said wheel may be arranged a scale in the form of numbers, each position of the stops having a number of its own, the scale being, therefore, partly upon one thumb wheel 36 and partly upon the other; and

A suitable pointers or indexes 37 may be providedV for said scales, said pointers being mounted on thepbrackets 37a which are fast on the typewriter carriage and yform the journals for the shafts 30, 31. VThe blades or carriers 27 may be guided inupper and lowerracks 38, 39, the upper rack preferably having notches 40 uponVV its front Vand rear edges, to receive the forks 41 with which the blade is formed, and being carried upon lbrackets 42 screwed upon the end of the lower rack 39; returning springs 43 for the column-stops being 'arranged within theforks and anchored in the Vupper rack bar 38.

The lower rack `39 may consist of notches 44 cutA in thefront of a bar 45,

which is supported upon brackets 46 car-V :mechanism Vtion, as seen at the upper part of Fig. 3 or the lower part of Fig. 2'; and the-spring detents 33, by cooperation with the abrupt faces lof the ratchet-wheel teeth 35, may lock the spur shafts againstbeing turned backwardly by V"the tension of said springs 43, which are'provided forJreturning the column-stops. c

In orderto avoidany possibility of confusion on the part of the typist ifi-moving the handles'36, one handle be placed at the right-hand end ofthe carriage, and the other at the left-hand end.

Variations may be resorted to within the scope of the invention,- and portions ofthe improvements may be used Without others.
